摘要：

Infrared (vibrational) circular dichroism (VCD) has been observed for the DNA models d(CG)5, poly(dG-dC)•poly(dG-dC), poly(dG)•poly(dC), poly(dA-dT)•poly(dA-dT), and poly(dA)•poly(dT) in the B-conformation in buffered, aqueous solution. The observed results are quantitatively interpreted in terms of the exciton model for coupled carbonyl stretching vibrational states. © 1990, American Chemical Society. All rights reserved.
